Given numbers are 639, 607, 243, 767
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 607) = 387873
GCD(639, 607) = ( 639 x 607 ) / 387873
= 639 / 607
= 639
Step2:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
Step3:
LCM(1, 767) = 767
GCD(1, 767) = ( 1 x 767 ) / 767
= 1 / 767
= 1
So, Greatest Common Divisor of 639, 607, 243, 767 is 1
